So I am storing my files in a database. Don't ask why, just know that I am not in control of this. Next, I am able to successfully store them as a hexidecimal representation and then spit them back for display with no problem, but then I attach them to an email using PHPMailer and they get sent properly with the right name and all, but they are corrupted. I will walk you through step by step below so that you know exactly how it is being stored, and this may help me debug my issue. (Please note that all code is paraphrased to save space and only show what is needed)
STEP 1
File is grabbed and then processed
$name = $_FILES['file_data']['name'];
$file = prepareImageDBString($_FILES['file_data']['tmp_name']);
$mime_type = $_FILES['file_data']['type'];
name, file, and mime_type are stored
here is the function prepareImageDBString()
function prepareImageDBString($filepath){
$out = 'null';
$handle = #fopen($filepath, 'r');
if($handle){
$content = #fread($handle, filesize($filepath));
$content = bin2hex($content);
#fclose($handle);
$out = $content;
}
return $out;
}
STEP 2
When the file is being viewed I show it as an embedded object. This file is small so I just posted the whole code. Do note that the file shows up with no problems here.
$q = "SELECT lease_doc_file_data FROM lease_doc_file WHERE lease_doc__id ='".$_GET['id']."'";
$file = "";
foreach($CONN->query($q) as $row){
$file = $row['lease_doc_file_data'];
}
if(!empty($file)){
header("Content-type: application/pdf");
ob_clean();
flush();
echo hextobin($file);
}
Here is the function hextobin()
function hextobin($hexstr){
$n = strlen($hexstr);
$sbin = "";
$i = 0;
while($i < $n){
$a = substr($hexstr,$i,2);
$c = pack("H*", $a);
if ( $i == 0 ){ $sbin = $c; }
else { $sbin .= $c;}
$i += 2;
}
return $sbin;
}
STEP 3
Finally the part where I go to send it as a mailer.
$q = "SELECT lease_doc_file_data, lease_doc_file_name, lease_doc_file_type FROM lease_doc_file WHERE lease_doc__id ='$id'";
$file_data = "";
$file_name = "";
$file_type = "";
foreach($CONN->query($q) as $row){
$file_data = $row['lease_doc_file_data'];
$file_name = $row['lease_doc_file_name'];
$file_type = $row['lease_doc_file_type'];
}
$file_data = hextobin($file_data);
$mail->AddStringAttachment($file_data, $file_name, 'binary', $file_type);
So this is the three step process and I"m not sure where the error is coming from. Hopefully someone can help! Thank you for all help in advance!

I was working on the eCommerce site and uploading the CSV file in the PHP database of Size that having the comma. The outcome of the result is the database is coming up with backward slash and double-quotes.
Please help me in rectifying that issue as had wasted my two days working on it.

Problem
You have an error in this line:
$foot_size = trim(addslashes($data[2]), '"');
What it does is to first escape double quotes:
"35,36,34" --> \"35,36,34\"
And then trim them:
\"35,36,34\" --> \"35,36,34\
Solution
Depending on if you actually want to have the quotes stored in your DB or not, call either trim or addslahes (but not both) or none of the two:
Strip quotes:
$foot_size = trim($data[2], '"');
Keep quotes:
$foot_size = $data[2];
# your framework *might* require explicitly escaping of quote chars:
$foot_size = addslashes($data[2]);
# even better:
$foot_size = $database->escape_string($data[2]);
I'm trying to get an image from an E-mail which is sent to my mailserver and save the file to the server. I tried it with this code:
$no_of_occurences = 0;
$intStatic = 2;
$decode = imap_fetchbody($mbox, $val , null);
$no_of_occurences = substr_count($decode,"Content-Transfer-Encoding: base64");
$no_of_occurences--;
echo $no_of_occurences;
if($no_of_occurences > 0){
for($i = 0; $i < $no_of_occurences; $i++){
$strChange = strval($intStatic+$i);
$decode = imap_fetchbody($mbox, $val , $strChange);
$data = base64_decode($decode);
$x = 1;
$fName = './images/'.$ticketurl."_".$x. '.png';
while(file_exists($fName)){
$x++;
$fName = './images/'.$ticketurl."_".$x. '.png';
}
if($x==500){
$valid = false;
exit;
}
$file = $fName;
$success = file_put_contents($file, $data);
}
}
This code is working fine but only if you have one type of appendage in it. If you place one image inline the mail it is working. If you place one as an attachment, it also works. But if you got both (inline and as attachment) it's just getting one image and a second clean png file.
Any suggestions how to solve this behavior?
I'm trying to use Mailchimp's Export API to generate a CSV file of all members of a given list. Here' the documentation and the example PHP code they give:
$apikey = 'YOUR_API_KEY';
$list_id = 'YOUR_LIST_ID';
$chunk_size = 4096; //in bytes
$url = 'http://us1.api.mailchimp.com/export/1.0/list?apikey='.$apikey.'&id='.$list_id;
/** a more robust client can be built using fsockopen **/
$handle = #fopen($url,'r');
if (!$handle) {
echo "failed to access url\n";
} else {
$i = 0;
$header = array();
while (!feof($handle)) {
$buffer = fgets($handle, $chunk_size);
if (trim($buffer)!=''){
$obj = json_decode($buffer);
if ($i==0){
//store the header row
$header = $obj;
} else {
//echo, write to a file, queue a job, etc.
echo $header[0].': '.$obj[0]."\n";
}
$i++;
}
}
fclose($handle);
}
This works well for me and when I run this file, I end up with a bunch of data in this format:
Email Address: xdf#example.com
Email Address: bob#example.com
Email Address: gerry#example.io
What I want to do is turn this into a CSV (to pass to a place on my server) instead of echoing the data. Is there a library or simple syntax/snippit I can use to make this happen?
If the format simply like:
Email Address, xdf#example.com
Email Address, bob#example.com
Email Address, gerry#example.io
is what you after, then you can do:
$handle = #fopen($url,'r');
$csvOutput = "";
if (!$handle) {
echo "failed to access url\n";
} else {
$i = 0;
$header = array();
while (!feof($handle)) {
$buffer = fgets($handle, $chunk_size);
if (trim($buffer)!=''){
$obj = json_decode($buffer);
if ($i==0){
//store the header row
$header = $obj;
} else {
//echo, write to a file, queue a job, etc.
echo $header[0].', '.$obj[0]."\n";
$csvOutput .= $header[0].', '.$obj[0]."\n";
}
$i++;
}
}
fclose($handle);
}
$filename = "data".date("m.d.y").".csv";
file_put_contents($filename, $csvOutput);
The variable $csvOutput contains the CSV format string.
This ones on me. From now on you might want to actually read some documentation instead of copying and pasting your way through life. other's will not be as nice as i am. here's a list of file system functions from the php website. http://php.net/manual/en/ref.filesystem.php Getting the file output to the desired csv format is an exercise left to the reader.
$apikey = 'YOUR_API_KEY';
$list_id = 'YOUR_LIST_ID';
$chunk_size = 4096; //in bytes
$url = 'http://us1.api.mailchimp.com/export/1.0/list?apikey='.$apikey.'&id='.$list_id;
/** a more robust client can be built using fsockopen **/
$handle = #fopen($url,'r');
if (!$handle) {
echo "failed to access url\n";
} else {
$i = 0;
$header = array();
$output = ''; //output buffer for the file we are going to write.
while (!feof($handle)) {
$buffer = fgets($handle, $chunk_size);
if (trim($buffer)!=''){
$obj = json_decode($buffer);
if ($i==0){
//store the header row
$header = $obj;
} else {
//write data into our output buffer for the file
$output .= $header[0].': '.$obj[0]."\n";
}
$i++;
}
}
fclose($handle);
//now write it to file
$path = '/path/to/where/you/want/to/store/file/';
$file_name = 'somefile.csv';
//create a file resource to write to.
$fh = fopen($path.$file_name,'w+');
//write to the file
fwrite($fh,$output);
//close the file
fclose($fh);
}
So I have searched high and low for a relevant answer, and I have yet to find one, so I'm just going to ask the question myself. In my MySQL tables I have 5 columns of id, customer__id, file_data, file_name, mime_typethe relevant one here is file_data which is a type of LONGBLOB. Now from what I understand the size of files that a LONGBLOB can handle is pretty substantial but when I try to upload a file that is around 978 KB it fails, could it be that the dimensions of the image are too large (2048 x 1536)?
Here is the code for my uploader. It works very elegantly for things like excel sheets, pdf, word documents, and other stuff, but when it comes to images it fails:
<?php
require_once '../../inc/config.php';
$response = array();
$response['errors'] = false;
$id = $_REQUEST['id'];
if(!empty($_FILES)){
//set default data arrays
$names = array(); //stores file names
$files = array(); //stores the file data
$mime_types = array(); //store the file type as a mime type
//force each file name to the names array
foreach($_FILES['file']['name'] as $name){
array_push($names, $name);
}
//force the file data into its own array spot in the files array
foreach($_FILES['file']['tmp_name'] as $temp){
array_push($files, prepareImageDBString($temp));
}
//force the mimetypes into the mime_types array
foreach($_FILES['file']['type'] as $type){
array_push($mime_types, $type);
}
//process all three of the file arrays simultaneously so that no data is left out
for($i = 0; $i < count($names); $i++){
$file_name = $names[$i];
$file_data = $files[$i];
$mime_type = $mime_types[$i];
//set the query for the data to go into the note_file table in the database
$q = "INSERT INTO brb.files (customer__id, file_name, file_data, mime_type)
VALUES('$id', '$file_name', '$file_data', '$mime_type')";
//run the query
if($stmt = $CONN->prepare($q)){
//process any errors that may occur
if(!$stmt->execute()){
printf("Error Message: %s\n", $CONN->error);
}
}
}
}
echo json_encode($response);
function prepareImageDBString($filepath){
$out = 'null';
$handle = fopen($filepath, 'r');
if($handle){
$content = fread($handle, filesize($filepath));
$content = bin2hex($content);
fclose($handle);
$out = $content;
}
return $out;
}
?>
If someone could point me in the direction that would be fantastic. Please do not provide be an answer on why the practice is bad, I'm aware it's bad practice and know what proper practice is, this is a learning tool for myself and nothing more, just bear with me on it for a minute.
Thank you to everyone who provides help!
I need a script that is finding and then replacing a sertain line in a CSV like file.
The file looks like this:
18:110327,98414,127500,114185,121701,89379,89385,89382,92223,89388,89366,89362,89372,89369
21:82297,79292,89359,89382,83486,99100
98:110327,98414,127500,114185,121701
24:82297,79292,89359,89382,83486,99100
Now i need to change the line 21.
This is wat i got so far.
The first 2 to 4 digits folowed by : ar a catergory number. Every number after this(followed by a ,) is a id of a page.
I acces te id's i want (i.e. 82297 and so on) from database.
//test 2
$sQry = "SELECT * FROM artikelen WHERE adviesprijs <>''";
$rQuery = mysql_query ($sQry);
if ( $rQuery === false )
{
echo mysql_error ();
exit ;
}
$aResult = array ();
while ( $r = mysql_fetch_assoc ($rQuery) )
{
$aResult[] = $r['artikelid'];
}
$replace_val_dirty = join(",",$aResult);
$replace_val= "21:".$replace_val_dirty;
// file location
$file='../../data/articles/index.lst';
// read the file index.lst
$file1 = file_get_contents($file);
//strip eerde artikel id van index.lst
$file3='../../data/articles/index_grp21.lst';
$file3_contents = file_get_contents($file3);
$file2 = str_replace($file3_contents, $replace_val, $file1);
if (file_exists($file)) {
echo "The file $filename exists";
} else {
echo "The file $filename does not exist";
}
if (file_exists($file3)) {
echo "The file $filename exists";
} else {
echo "The file $filename does not exist";
}
// replace the data
$file_val = $file2;
// write the file
file_put_contents($file, $file_val);
//write index_grp98.lst
file_put_contents($file3, $replace_val);
mail('info#', 'Aanbieding catergorie geupdate', 'Aanbieding catergorie geupdate');
Can anyone point me in the right direction to do this?
Any help would be appreciated.
You need to open the original file and go through each line. When you find the line to be changed, change that line.
As you can not edit the file while you do that, you write a temporary file while doing this, so you copy over line-by-line and in case the line needs a change, you change that line.
When you're done with the whole file, you copy over the temporary file to the original file.
Example Code:
$path = 'file';
$category = 21;
$articles = [111182297, 79292, 89359, 89382, 83486, 99100];
$prefix = $category . ':';
$prefixLen = strlen($prefix);
$newLine = $prefix . implode(',', $articles);
This part is just setting up the basics: The category, the IDs of the articles and then building the related strings.
Now opening the file to change the line in:
$file = new SplFileObject($path, 'r+');
$file->setFlags(SplFileObject::DROP_NEW_LINE | SplFileObject::SKIP_EMPTY);
$file->flock(LOCK_EX);
The file is locked so that no other process can edit the file while it gets changed. Next to that file, the temporary file is needed, too:
$temp = new SplTempFileObject(4096);
After setting up the two files, let's go over each line in $file and compare if it needs to be replaced:
foreach ($file as $line) {
$isCategoryLine = substr($line, 0, $prefixLen) === $prefix;
if ($isCategoryLine) {
$line = $newLine;
}
$temp->fwrite($line."\n");
}
Now the $temporary file contains already the changed line. Take note that I used UNIX type of EOF (End Of Line) character (\n), depending on your concrete file-type this may vary.
So now, the temporary file needs to be copied over to the original file. Let's rewind the file, truncate it and then write all lines again:
$file->seek(0);
$file->ftruncate(0);
foreach ($temp as $line) {
$file->fwrite($line);
}
And finally you need to lift the lock:
$file->flock(LOCK_UN);
And that's it, in $file, the line has been replaced.
Example at once:
$path = 'file';
$category = 21;
$articles = [111182297, 79292, 89359, 89382, 83486, 99100];
$prefix = $category . ':';
$prefixLen = strlen($prefix);
$newLine = $prefix . implode(',', $articles);
$file = new SplFileObject($path, 'r+');
$file->setFlags(SplFileObject::DROP_NEW_LINE | SplFileObject::SKIP_EMPTY);
$file->flock(LOCK_EX);
$temp = new SplTempFileObject(4096);
foreach ($file as $line) {
$isCategoryLine = substr($line, 0, $prefixLen) === $prefix;
if ($isCategoryLine) {
$line = $newLine;
}
$temp->fwrite($line."\n");
}
$file->seek(0);
$file->ftruncate(0);
foreach ($temp as $line) {
$file->fwrite($line);
}
$file->flock(LOCK_UN);
Should work with PHP 5.2 and above, I use PHP 5.4 array syntax, you can replace [111182297, ...] with array(111182297, ...) in case you're using PHP 5.2 / 5.3.
